铅酸蓄电池制造的基本目的是要获得极板上活性物质的最大工作面积。要求极板薄，同一槽内可多装极板片数，可以得到极大工作面积。要想将极板作薄，首先就得将板栅作得很薄。因此作为板栅材料的合金的物理性质、化学性能对板栅生产显得相当重要。板栅作为极板的“骨架”与导电汇流体系，是活性物质的机械支持体，与此同时它还是电流的主要通道，板栅的基本要求与综合性质需要生产板栅的合金的某些特性来确保。板栅应有足够的硬度与强度，能经受起电池制造过程与使用过程的机械应力与热应力的作用，并能保持板栅原有的外形，蠕变应小，腐蚀要小。
The basic purpose that the lead sour storage battery makes wants to acquire the biggest work area of the pole plank top activity material.Requesting pole plank is biggest thin, can pack more very the plank number inside the same slot, can get work area.To want to make the pole plank thin have to make plank grid first very thin.It consequently is the physical property, chemistry function of the metal alloy of plank grid material to seem to be very important to the plank grid production.The plank grid is the pole knothole"framework" and conduct electricity to remit fluid to fasten, the machine of activity material to support a body, it is still the main passage of electric current meanwhile, the basic request of plank grid with comprehensive the property need to produce some characteristics of the metal alloy of plank grid to ensure.The plank grid should have enough degree of hardness and strength, can experience to have the machine of the battery manufacturing process and use process in response to the dint and the heat in response to the function of dint, and can keep the shape that the plank grid originally possessed, Ru's changing should be small, decay have to be small.
